First of all, the UV range is resonant with electronic transitions of many small molecules with fairly simple excited state energy level structure, whose photoinduced dynamics can be accurately modeled using ab initio computational approaches; ultrafast TA spectroscopy in the UV can thus be used to ...
the ultraviolet (UV, λ < 400 nm) and deep-ultraviolet region (DUV, λ < 200 nm) regions by all-solid-state lasers, owing to its great application in many scientific and engineering fields such as semiconductor photolithography, micromachining and ultraprecise photoelectron spectrometry [8–11]....
Microscopic and spectroscopic characterization techniques, including atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS), were used to investigate the morphological and electrical modification of the MoS2 surface after CHF3 plasma treatment. This work suggests the potential application ...
Chemical changes of the PEEK surfaces were analysed using X-ray photoelectron spectroscopy (XPS). EUV radiation and nitrogen plasma treatment caused significant changes in the topography of modified PEEK's surfaces and an increase in their average roughness. Strong chemical decomposition, appearance of ...

Structural changes of the polymer and MWCNTs were observed by means of X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. The XPS results revealed that scission of the C–Cl bonds of the chloromethyl groups and benzyl-type radical formation occurred. The incremental surface defects of ...
